Young scholars investigate arctic geology and hydrology as well as tundra ecology as they consider options for sewage treatment. Public safety, environmental impact, and issues of construction and engineering be explored.

Students investigate the types of genetically modified crop plants there are and the benefits and risks of such plants. The agricultural needs in developing nations for this biological knowledge to resolve societal issues is also...

Pupils investigate the relationships between protozoa, algae and monera in freshwater, shoreline soil, and reindeer rumen. They publish reports of their findings.

Students investigate the characteristics of the tundra on the North Slope of Alaska. They conduct Internet research, develop a chart of the types of vegetation, plant growth, and fauna found on the tundra, identify examples in their own...

Fifth graders investigate the concept of natural resources. They participate in a simulation project to see possible uses. They use the internet to study how Hacienda Verde is used as a model for others for sustainable coffee crops.

Third graders investigate pollution. They discuss pollution and its effects. They create a Venn diagram of pollution and people polluting. They create a landfill and predict what will occur over a week's time. They create two air...

Students investigate water ways by conducting an experiment with classmates.  In this natural resources lesson, students define a watershed and identify where large ones are located within the United States.  Students utilize...

Learners investigate water as an agent of change. They conduct an experiment involving a mound of soil, observe and record any changes that occur when ice melts on the mound of dirt, and create a drawing of the changes that take place...

Fourth graders explore the agents of erosion. They observe rocks that are rough and unweathered and record observations. They investigate rocks rubbed with sandpaper and ones that are not and the effects that the sandpaper has on the...

Students study the geologic history of terrain, soils, and drainage patterns. They recognize ecological processes that determine the dynamic nature of habitats. They investigate the influence of human activity on the landscape.

Learners explore coffee production.  In this cross-curriculum rainforest ecology lesson, students research regions where coffee comes from and investigate how the native birds in the rainforest are effected by coffee...

Students investigate what causes the heat on Earth.  In this Earth heating lesson plan, students experiment with different heat sources and determine where the Earth gathers the most heat.  Students explore vocabulary words...

Learners investigate, through their own experimentation, the important role wildlife play in nutrient cycling. Earthworms and compost are used in this experiment and different experimental setups be evaluated.

Students investigate ways that animals adapt to their environments through hands-on activities using isopods and an interactive video.

Middle schoolers investigate the three methods of waste disposal. They listen to a teacher-led lecture, answer discussion questions, and write a letter to the E.P.A. from the viewpoint of an environmental engineer.

Students use microscopes to investigate the diversity of life that exists in pond water. They then conduct a controlled investigation to study the effect of a pollutant (rice) on a microcosm ecosystem.

Students investigate how polluted water is filtered so people can use this recycled resource. They conduct an experiment in which they put "polluted" water through a filtering system. They investigate what happens at a water treatment...

Students investigate mixtures made of water and familiar solid materials. They observe and discuss the changes that occur immediately and set the mixtures aside for a day. Finally, students observe the mixtures, note changes, and graph...

Students examine succession in different communities.  In this investigative lesson students study ecological succession and complete several assignments. 

Young scholars investigate th anatomy of a flower. They investigate the structures and processes by which flowering plants generate pollen, ovules, seeds, and fruit through dissection,

Young scholars investigate the concept of caves by conducting an experiment. The lesson plan contains background information for the teacher. They collect data while making observations and write a review of the concept once the...

Fourth graders discover the differences between: reduce, reuse, and recycle by performing hands on examinations. They list what would happen to the soil if we allowed the earth to wash away and briefly discuss the meaning of erosion.

Fifth graders investigate how humans pollute the water supply with a number of different contaminates. While working in small groups they examine screening, sedimentation, filtration, and chemical treatments as methods of water treatment.

Students investigate the concept of groundwater that includes aquifers, groundwater flow, and the water table. They participate in activities using a flow demonstration model. Its use engages all types of learners because of its hands on...
